You can see rig specs below. I am using a legal copy of Vista Ultimate 32 bit SP1. I wiped a new drive then installed said OS. Before upgrading to SP1, I could not update at all. I was receiving some strange error that nobody and I mean nobody had a solution for, not even the wonderful people at microsoft/support. I decided to download and install SP1 on its own hoping it would fix the problem. It did, sort of. Everthing went as it should and after a quick reboot I was now running SP1. I decided to check if the update through vista was working now. Everything looked great so I decided to try to download and install a few of the "optional" updates that are available. It now gets to about 25% of the install before kicking me to the BSOD which states:DRIVER_IRQL_NOT_LESS_OR_EQUAL ***Stop: 0x000000D1 (0x00000000, 0x00000002, 0x00000000, 0x80737395) ***nvstor.sys - Address 80737395 base at 80733000, Datestamp 40671a61 then it does the memory dump and I have to do a manual restart. This happens if I am trying to download 1 or 20 "optional" updates, it makes no difference how I select or try at this. I had no issues running XP Pro SP2 nor have I seen this BSOD before. It did not do this prior to installing SP1. Any ideas?
